Figure 1. Canonical variate analysis <strong>of</strong> 5 tooth characteristics for P.c. azteca, P.c. browni, P.c. californica, P.c. kaibabensis<br />
illustrating a lack <strong>of</strong> separation between <strong>the</strong>se subspecies based on dentition.<br />
that a subspecies carries (ecologically relevant) adaptations<br />
couples with <strong>the</strong> potential to become a unique new species<br />
are compelling reasons for affording <strong>the</strong>m protection<br />
against extinction."<br />
Because <strong>the</strong> Endangered Species Act requires <strong>the</strong><br />
conservation <strong>of</strong> subspecies, we recognize <strong>the</strong> constraints<br />
that <strong>the</strong> law imposes on wildlife and land managers.<br />
However, among widely dispersing mammals which do not<br />
appear to be separated by geographic barriers <strong>the</strong> subspecies<br />
category may be ei<strong>the</strong>r too ambiguous or simply<br />
inappropriate as a management designation. From a<br />
standpoint <strong>of</strong> conservation biology, using <strong>the</strong> <strong>mountain</strong> <strong>lion</strong><br />
as an umbrella species with consideration for habitat<br />
continuity and connectivity may be a more useful<br />
management strategy.<br />
The question <strong>of</strong> taxonomic status, cast into doubt<br />
by ecological evidence, may only be resolved through <strong>the</strong><br />
examination <strong>of</strong> a larger morphometric data set, and through<br />
<strong>the</strong> application <strong>of</strong> modern genetic and statistical techniques.<br />
It is unlikely that any single ecological, morphological, or<br />
genetics-based approach will or should answer <strong>the</strong> question<br />
<strong>of</strong> subspecific status.<br />
